BURNER FOR GAS-STOVES.

SPECIFICATION forming part of Letters Patent No. 225,740, dated. March 23, 1880,

Application filed January 21, 1880. Y

To all whom it may concern:

Be it known that I, WILLIAM BLIESNER, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Burners for Gas Stoves, of which the foilowing is a full, clear, and exact description, reference being bad to the accompanying drawings, forming part of this specification.

My improvement relates to a burner for gasstoves applicable, by a change in dimensions, for consumption of gasoline or ordinary city gas; and my improvement consists in the novelties described in the claims to this specification.

In the drawings, Figure 1 is a perspective view with part of the removable deflector broken away to show the parts beneath. Fig. 2 is a vertical section axial to the burner. Fig. 3 is an enlarged detail section, showing the burner arranged for consumption of city gas.

A is the case, standing on legs 0, and having at top bars B to support the cooking-vessels. I make the bars B extend outward a sufflcient distance to support two or more ordinary cookin g-vessels, and th-eflame is deflected outward to the same by a removable disk or deflector, D. The deflect-or D rests in depressions b at the inner ends of the bars B.

E is the feed-pipe, extending from a raised reservoir, as usual, and screwing into a casting, F, having a passage, f, leading to the burner pipe or casting G. The burner proper, H, forms part of this casting, and has a screwthreaded socket, in which screws the stem i of the valve I. The valve is turned by a handle, I.

2" represents the conical needlepoint for guiding the rod and regulating the amount of valve-opening. The port or valve-seat ending in jet-hole J is made to fit the needle-point of the valve.

The burner is slightly inclined upward from the horizontal plane to the jet-hole, so as to give the flame and jet a slightly-upward tendency, but yet so as to allow a long cylindrical combustion chamber, and to admit of the handle of the valve to be near the top of the case and the valve-stem in line with the jet. The jet and flame enter a combustion-chamber, K, in line with the burner, and consequently inclined somewhat from a horizontal plane.

L is a flame passage extending upward from the inner end of the combustion-chamber, and leading into another combustionchamber whose floor is formed by the diskshaped top F of the casting F, and whose top is formed by the removable metal dome M, standing upon a number of legs, m, around its margin.

Surrounding the circular series of legs m is a circular series of studs, N, in close contact with the legs, and having sufl'icient width to close or nearly close the openings between the legs. The arrangement is such that the openings between the legs may be regulated in size by turning the dome M. The turning movement of the dome is limited by a stud, 0, extending outwardly from its margin between two of the studs N, set far enough apart to allow the necessary movement.

The upper part of the dome may have a cylindrical part, M, which may have a number of horizontal holes, m, for the passage of flame; but the said part M, with its holes m, is not an essential part of the invention.

The modification shown in Fig. 3 has no es sen tial change from the devices shown in Figs. 1 and 2. The jet-hole J and valve-port are made larger than in the latter figures, to allow the passage of city gas in sufflcient quantity.

When city gas is used the hose or pipe supplying the gas is coupled to pipe E.

The operation is as follows when gasoline is used: The valve I is opened a little distance and the liquid passing through the jet-hole is ignited. The casting F soon gets so heated as to vaporize the gasoline in the combustionchamber, and even in the passage f, and the flame fills this chamber K, (where the gas mingles with the air carried in with the jet,) and the flame and partly consumed gas ascend into the upper chamber, F M. More or less free exit is given to the flame by regulating the size of the openings between the legs on. This is an important feature, because the size of the openings should bear proportion to the quantity of gas burned and consequent amount of flame. Thus, where only a small flame is used, it the openings between legs m are of full size, the flame will go out, (proba bl; from the influx of air.) To prevent the extinction of the flame the passages must be reduced in size according'to the size of the flame.

When several vessels are used for cooking, the deflector D is used to direct the flame beneath the vessels.

I claim as my invention- 1. The casting F, having inclined combustion-chamber K and approxiniately-parallel passage f, provided with screwthreaded sockets, in combination with supply-tube Erburner H, and dome M, substantially as and for the purpose described.

2. The combination, with the burner H, combustion-chambers K and F M, and dome-top M of the notched bars B and removable deflector D, of greater diameter than the dome, substantially as set forth.

WILLIAM BLIESNER.
